11 Things You Might Not Know About J.K. Rowling

AKA the most interesting Muggle in the world.

J.K. Rowling met a Hell's Angel biker who later became the inspiration for Hagrid.

According to Robbie Coltrane who plays Hagrid, he was "based on a Hell's Angel she knew in the West Country. ...He was just huge and terrifying. And then he would sit down and talk about his garden and how his petunias had been very bad that year."

J.K. Rowling never specifically brought up religion in Harry Potter because she was afraid her Christian readers would be able to guess the ending.

"To me [the religious parallels have] always been obvious," she said. "But I never wanted to talk too openly about it because I thought it might show people who just wanted the story where we were going."

She included Hedwig's death in Deathly Hallows because it signaled the end of Harry's innocence.

"The loss of Hedwig represented a loss of innocence and security. She has been almost like a cuddly toy to Harry at times. Voldemort killing her marked the end of childhood. I’m sorry… I know that death upset a LOT of people!"

Rowling turned down a Michael Jackson-produced musical of Harry Potter.

"Michael Jackson wanted to do a musical. I said no to a lot of things. For me, I love the films, I love the books, and there's elements that I love around it...but I only wanted to do it because I knew it would be incredible."
